[0002] In some high-risk areas where electrical equipment operates, non-professional or unauthorized personnel are prohibited from entering for personal safety reasons. For example, during startup tests in the waterwheel room, the rotation of related mechanical parts may cause safety accidents such as personal injury. Also, during equipment maintenance, when the door of the original thrust bearing room is removed, the door openings of the waterwheel room and thrust bearing room form a high-risk side chamber, posing a risk of falling. Unlike construction sites, the method of deploying supervisors on-site to control access to these equipment rooms has shortcomings such as site limitations, interference with daily operations and maintenance and the handling of large items, high labor costs caused by long-term supervision, and incomplete supervision.

[0003] Therefore, in these high-risk areas, how to conveniently and intelligently control the entry and exit of people has become an urgent problem to be solved. Summary of the Invention

[0024] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0025] Please refer to Figures 1 to 3 , a safety protection fence, comprising a mounting base 1 and a horizontal extension device for forming a fence;

[0026] The horizontal extension device includes a control console 2, a rotation drive member 3 and at least two flip connectors 4, and the control console 2 is located on the mounting base 1;

[0027] All the flip connectors 4 are arranged on the console 2 in a horizontal direction away from the console 2. Adjacent flip connectors 4 are rotatably connected to each other, so that all the flip connectors 4 form a foldable and telescopic structure. The rotation driving members 3 are respectively provided on the flip connectors 4. The rotation driving members 3 are used to control the rotation of the flip connector 4 relative to another adjacent flip connector 4.

[0028] The flip connector 4 is provided with an infrared sensor, and a detection end of the infrared sensor is arranged in a vertical direction away from the flip connector 4 . The console 2 is electrically connected to all the rotating drive members 3 .

[0029] From the above description, it can be seen that the beneficial effects of the present invention are: providing a safety protection fence, installing the equipment at the entrance and exit of a high-risk area by installing a base 1, and utilizing a foldable and telescopic fence composed of multiple flip connectors 4 with freely adjustable length, and utilizing infrared sensors to form an invisible detection network in the vertical direction of the fence. When unverified personnel or objects pass by, an alarm is triggered. The combined use of the flip connector 4 and the infrared detector can achieve comprehensive detection while reducing costs and space occupation volume. Combined with the real-time control of the software of the console 2, real-time and comprehensive access control is implemented for high-risk areas to ensure the safety of personnel and equipment operation.

[0030] Furthermore, the horizontal extension device further includes an identification camera;

[0031] The identification camera is located on the mounting base 1 , and the console 2 is electrically connected to the identification camera.

[0032] From the above description, it can be seen that setting up an identification camera can not only perform facial recognition verification on personnel, but also understand the external conditions of the current personnel, such as the type of equipment they carry, so as to cooperate with the infrared detector to retain the detection function of other positions while releasing them to prevent loopholes; at the same time, it can record the video of people entering and leaving for subsequent verification.

[0033] Furthermore, the horizontal extension device further includes a fixing seat 5, a first connecting member 6 and a second connecting member 7;

[0034] The first connecting member 6 is provided on the flip connecting member 4 farthest from the console 2 , and the second connecting member 7 is located on the fixing seat 5 . The first connecting member 6 and the second connecting member 7 are detachably connected.

[0035] From the above description, it can be seen that the fixing seat 5 and the mounting base 1 can be set on the left and right sides of the entrance and exit of the high-risk area; when the fence is fully unfolded, the first connecting member 6 and the second connecting member 7 on the flip connecting member 4 at the farthest end can be detachably connected, thereby fixing and locking the fence to prevent it from being forcibly pulled open by external force.

[0036] Furthermore, the horizontal extension device further includes a limiting member 8;

[0037] The limiting member 8 is provided on the mounting base 1;

[0038] When all the flip connectors 4 are in the folded state, the limiting member 8 is detachably connected to the flip connector 4 farthest from the console 2 .

[0039] It can be seen from the above description that, compared with the above-mentioned unfolding process, when the fence is in the retracted state, the limiting member 8 is also used for fixing to ensure the stability and safety of the fence.

[0040] Furthermore, the horizontal extension device further includes a hollow shaft 9;

[0041] The flip connector 4 is rotationally connected to the adjacent flip connector 4 via the hollow shaft 9 , the rotation driving member 3 is transmission-connected to the hollow shaft 9 , and the infrared sensor is disposed in the hollow shaft 9 .

[0042] From the above description, it can be seen that a rotatable hollow shaft 9 is used for transmission between adjacent flip connectors 4; at the same time, the infrared sensor is located inside the hollow shaft 9 and adopts a hidden design, which not only makes the fence appearance neat and beautiful, but also provides protection for the infrared sensor.

[0043] Furthermore, two infrared sensors are provided in each hollow shaft 9;

[0044] The two infrared sensor detection ends in the same hollow shaft 9 are oriented in opposite directions, and the directions of the two infrared sensor detection ends are both parallel to the axial direction of the hollow shaft 9 .

[0045] From the above description, it can be seen that the infrared sensing lines of the two infrared sensors are spread up and down relative to the flip connector 4, so as to achieve real-time and comprehensive capture of objects.

[0046] Furthermore, a human body sensor is included. The human body sensor is arranged on the mounting base 1 and is electrically connected to the console 2 .

[0047] From the above description, it can be seen that a human body sensor is set to control the console 2 to enter the working state when someone approaches, ensuring that the console 2 responds in time.

[0048] Please refer to Figure 4 A method for operating a safety fence is applied to the above-mentioned safety fence and is characterized by comprising the following steps:

[0049] S1. Control all the flip connectors 4 to rotate by all the rotating drive members 3 so that the horizontal extension device reaches the maximum horizontal extension distance, forming a fence across the entrance and exit of the high-risk area;

[0050] S2, activating the infrared sensor on each of the flip connectors 4, so that all of the infrared sensors form an infrared detection network in the vertical direction of the entrance and exit;

[0051] S3. If the infrared sensor detects that an object has passed through, an alarm is triggered;

[0052] S4. When a person needs to pass, obtain the person's verification information and perform verification;

[0053] S5. If the person passes the verification, the flip connector 4 is controlled to rotate so that the horizontal extension device is folded and contracted to open the fence.

[0054] From the above description, it can be seen that the beneficial effects of the present invention are: a foldable and telescopic fence composed of multiple flip connectors 4 is used to form a freely adjustable length, and an infrared sensor is used to form an invisible detection network in the vertical direction of the fence. When an unverified person or object passes by, an alarm is triggered. The combined use of the flip connector 4 and the infrared detector can achieve comprehensive detection while reducing costs and space occupation volume. Combined with the real-time control of the software of the console 2, real-time and comprehensive access control is implemented for high-risk areas to ensure the safety of people and equipment operation.

[0055] Furthermore, the step S5 specifically includes:

[0056] S51. If the person passes the verification, the horizontal width required for the person to pass through the fence is calculated based on the image of the recognition camera;

[0057] S52 , controlling the rotation of the different flip connectors 4 so that the horizontal extension device contracts by a distance that matches the size of the horizontal width, while maintaining the detection function of the infrared sensor.

[0058] From the above description, it can be seen that when allowing people to pass, the fence's retraction length is controlled by the required distance based on the people and the equipment they carry, thereby forming a restriction. At other locations, the infrared sensor is still in the detection state to prevent other people from passing through at the same time as the verified people, and to facilitate automatic one-by-one screening.

[0059] Furthermore, before step S4, the following steps are further included:

[0060] The human body sensor senses whether there is a person approaching, and if so, the control console 2 enters the working state.

[0061] It can be seen from the above description that when someone approaches, the control console 2 enters the working state to ensure that the console 2 responds in time.

[0062] Please refer to Figures 1 to 3 , embodiment 1 of the present invention is:

[0063] A safety protection fence includes a mounting base 1 and a horizontal extension device for forming a fence; the horizontal extension device includes a control console 2, a rotating drive member 3 and at least two flip connectors 4, and the control console 2 is located on the mounting base 1; all flip connectors 4 are arranged on the control console 2 in a horizontal direction away from the control console 2, and adjacent flip connectors 4 are rotatably connected so that all flip connectors 4 form a folding and telescopic structure, and the rotating drive members 3 are arranged on the flip connectors 4 in a one-to-one correspondence, and the rotating drive members 3 are used to control the rotation of the flip connector 4 relative to another adjacent flip connector 4; an infrared sensor is provided on the flip connector 4, and the detection end of the infrared sensor is set in a vertical direction away from the flip connector 4, and the control console 2 is electrically connected to all the rotating drive members 3.

[0064] The safety fence of this embodiment can be flexibly fixed to high-risk areas such as the outer edges of the door openings of the waterwheel chamber and the thrust bearing chamber. Due to its foldable and telescopic structure composed of multiple flip connectors 4, it can be folded and stored when not in use, ensuring that daily operation and maintenance of the waterwheel chamber and the smooth transportation of large items are not hindered.

[0065] And, as Figure 1 and Figure 2As shown, the horizontal extension device also includes a hollow shaft 9; the flip connector 4 is rotatably connected to the adjacent flip connector 4 through the hollow shaft 9, the rotating drive member 3 is transmission-connected to the hollow shaft 9, and the infrared sensor is set in the hollow shaft 9. Two infrared sensors are set in each hollow shaft 9; the detection ends of the two infrared sensors in the same hollow shaft 9 face in opposite directions, and the detection directions of the two infrared sensors are parallel to the axial direction of the hollow shaft 9. After the flip connector 4 is unfolded, it forms a stable fence, and combined with the infrared sensor, it constructs a virtual and real safety net, as shown in FIG. Figure 3 As shown by the arrow.

[0066] The rotating drive element 3 can be a micro-servo, with the servo's wiring and other components housed within the hollow shaft 9. Furthermore, to enhance visibility, a light strip can be provided on the horizontal extension device, powered and controlled by the control console 2. When the fence is fully extended, the light strip illuminates, providing a clear warning.

[0067] In this embodiment, combined with Figure 1 and Figure 2 As shown, the horizontal extension device also includes a fixing base 5, a limiting member 8, a first connecting member 6, and a second connecting member 7; the first connecting member 6 is arranged on the flip connecting member 4 farthest from the console 2, and the second connecting member 7 is located on the fixing base 5. The first connecting member 6 and the second connecting member 7 are detachably connected. The limiting member 8 is arranged on the mounting base 1;

[0068] When the fence is fully unfolded, the first connector 6 and the second connector 7 on the flip connector 4 farthest from the console 2 are detachably connected to fix the fence; and when the fence is in a folded state, the limiter 8 is detachably connected to the flip connector 4 farthest from the console 2. The first connector 6, the second connector 7 and the limiter 8 can all be composed of components such as smart locks. In addition, in order to ensure that the fence can be opened normally, the system is equipped with a special key. Use the special key to unlock the lock hole of the second connector 7 and the lock hole of the limiter 8. Press the execution button on the lock to open all the lock tongues of the two locks. Since the fence is a folding and telescopic structure, once the lock is unlocked, the fence can be directly opened manually to ensure quick passage in an emergency.

[0069] In addition, the console 2 is the core component of the entire system, responsible for receiving and processing various signals and controlling the operation of the fence and locks. The console 2 is installed on the side of the door opening and is equipped with a series of advanced equipment, which are described below:

[0070] 1. Small touch screen

[0071] Users can use the touch screen to select fence commands, such as expand or collapse, and enter a password to verify their identity. This intuitive operation allows users to easily control the movement of the fence.

[0072] 2. Human body sensor

[0073] When a person approaches the console 2, the human body sensor will trigger the console 2 to enter the working state to ensure timely response of the system.

[0074] 3. Identify the camera

[0075] The recognition camera uses an AI high-definition smart camera that can capture clear images of people approaching the fence and confirm whether they are authorized personnel through image recognition technology.

[0076] 4. Voiceprint collection terminal and electronic identity recognition device:

[0077] Together, these two devices form a two-factor authentication system. The voiceprint acquisition terminal collects and verifies the individual's voiceprint, while the electronic identification device confirms the individual's identity. Only after successful two-factor authentication will the system grant authorized personnel access to the waterwheel or thrust bearing room.

[0078] 5. Alarm player

[0079] When someone attempts to enter illegally, the alarm player will emit a loud alarm to warn the trespasser and alert the on-duty personnel.

[0080] 6. Memory

[0081] The memory stores information such as the authorized person's voiceprint, face, and body movements for authentication and permission management. This enables the system to flexibly adapt to the needs of different scenarios, improving the system's practicality and security.

[0082] 7. Communication module

[0083] Console 2 communicates with the remote computer terminal through the communication module

[0084] The control system exchanges data with the remote computer terminal software through the communication module. This allows the remote computer terminal to monitor and control the operation status of multiple intelligent safety fence protection and dual identification systems in real time;

[0085] At the same time, the remote computer terminal and the identification device on the console 2 cooperate with each other to realize the remote dual authentication function. The remote computer terminal can also collect information such as the voiceprint, face, and body movements of authorized personnel, and manage tasks such as staff permissions and identity verification. This design can improve the intelligence level and management efficiency of the system.

[0086] The communication module is also responsible for transmitting various data collected by the console 2 (such as sensor readings, authentication information, fence status, etc.) to the remote computer terminal in real time. This ensures that remote managers can keep abreast of the on-site situation at any time. In order to ensure the integrity and consistency of the data, the communication module will regularly synchronize data with the remote computer terminal to ensure that the data on both ends is always kept up to date. The communication module adopts a standardized interface design, which enables it to seamlessly connect with other systems or devices, improving the scalability of the system. In order to adapt to different application scenarios and needs, the communication module supports multiple communication protocols (such as TCP / IP, UDP, etc.) to ensure wide compatibility. When the communication module detects a fault, it can automatically diagnose the cause of the fault and send a fault report to the manager through the remote computer terminal for timely processing. When necessary, managers can remotely maintain and upgrade the communication module through the remote computer terminal, greatly improving maintenance efficiency and system availability.

[0087] Furthermore, the remote computer terminal can send commands to Control Station 2 through the communication module, such as remotely controlling the deployment and retraction of the fence or modifying security parameters. The communication module is responsible for receiving these commands and ensuring their accurate transmission to Control Station 2 for execution. After executing the remote commands, the communication module provides real-time feedback on the execution results to the remote computer terminal, allowing management personnel to understand the execution status of the commands.

[0088] Furthermore, to ensure data transmission security, the communication module encrypts all transmitted data to prevent theft or tampering during transmission. The communication module features error detection and correction capabilities, enabling it to detect and correct errors during data transmission, ensuring data accuracy and integrity. The communication module employs various mechanisms to ensure communication stability, such as disconnection reconnection and data transmission confirmation, ensuring a stable connection even in complex environments.

[0089] Please refer to Figure 4 , the second embodiment of the present invention is:

[0090] A method for operating a safety protection fence, applied to a safety protection fence of embodiment 1, comprises the following steps:

[0091] S1. Control all the flip connectors 4 to rotate by all the rotating drive members 3 so that the horizontal extension device reaches the maximum horizontal extension distance, forming a fence across the entrance and exit of the high-risk area;

[0092] In this embodiment, as shown in the figure, the control console 2 controls each rotating driving member 3 in order from near to far, so as to unfold the folded flip connecting member 4.

[0093] S2, start the infrared sensor on each flip connector 4, and all the infrared sensors form an infrared detection network in the vertical direction of the entrance and exit;

[0094] S3. If an infrared sensor detects an object passing through, an alarm is triggered;

[0095] S4. When a person needs to pass, obtain the person's verification information and perform verification;

[0096] In this embodiment, when a person wants to approach the fence, the human body sensor senses whether there is a person approaching. If so, the control console 2 is controlled to enter the working state.

[0097] In this embodiment, the preferred identification and verification process is as follows:

[0098] When a worker approaches an entrance or exit, the identification process of console 2 is automatically triggered, as follows:

[0099] Facial recognition: The recognition camera immediately captures the worker's face and searches for it against a stored facial image library to confirm their identity. This step is the first layer of the recognition process.

[0100] If the facial recognition result shows that the person is not an authorized person, the system will immediately end the recognition process and will not perform subsequent operations. If the facial recognition confirms that the person is an authorized person, the system will proceed to the next step to perform human behavior recognition.

[0101] Human behavior recognition: The system requires the authorized individual to perform a specific gesture, such as a designated gesture for folding or unfolding, as a second layer of recognition. This ensures not only that the face is recognized but also that the behavior is as expected, increasing system security. If the authorized individual fails to perform the designated gesture correctly, the system may request a repeat gesture recognition or terminate the process. If gesture recognition is successful, the dual recognition process is complete, and Console 2 controls the fence to execute the corresponding command, such as folding or unfolding.

[0102] Furthermore, in the event of insufficient lighting or obstruction of facial features, making facial recognition impossible, the system can switch to an electronic identification device, such as an ID card and password for dual identification. Staff members must use an electronic identification device, such as a card reader, to swipe their ID card. The system will check the ID card information to confirm whether the person is an authorized person. If the identification result shows that the person is not an authorized person, the system will immediately end the identification process. If the person is identified as an authorized person, proceed to the next step. Next, the authorized person must enter the operation password on the console 2 screen. Once the ID card identification confirms that the person is an authorized person and the password is double-verified, console 2 will control the fence to execute the corresponding command.

[0103] Furthermore, duty rooms near high-risk areas can be remotely controlled. Because the duty room environment is stable, more accurate voiceprint recognition technology can be used. Duty personnel must first undergo voiceprint authentication using a voiceprint acquisition terminal as the first level of authentication. After passing voiceprint recognition, they must enter the operation password on the terminal software as the second level of authentication. Once both levels of authentication are passed, the duty personnel can remotely control the execution of fence commands.

[0104] S5. If the person passes the verification, the flip connector 4 is controlled to rotate so that the horizontal extension device folds and contracts, and the fence is opened.

[0105] In this embodiment, step S5 specifically includes:

[0106] S51. If the person passes the verification, the horizontal width required for the person to pass through the fence is calculated based on the image from the recognition camera;

[0107] S52 , controlling the rotation of different flip connectors 4 so that the horizontal extension device contracts by a distance that matches the horizontal width, while maintaining the detection function of the infrared sensor.

[0108] In summary, the safety protection fence and its operation method provided by the present invention have the following beneficial effects:

[0109] Multiple security protection: Combining physical fencing and infrared invisible door nets to form a double security protection. The physical fence provides actual barriers, while the infrared invisible door nets provide additional electronic protection without affecting access.

[0110] Flexible deployment and folding mechanism: The fence can be quickly deployed or folded according to actual needs, which can provide sufficient protection space during maintenance or special circumstances, and can be compactly folded when not needed to save space.

[0111] Accurate identification and authentication system: Through cameras and human body sensing technology, the fence can accurately identify authorized and unauthorized personnel, ensuring that only authorized personnel can enter the fenced area.

[0112] Powerful remote management capabilities: The fence can be connected to a remote computer or control center to achieve remote monitoring, control and management, greatly improving management efficiency and response speed.

[0113] Complete alarm and notification system: Once an illegal intrusion or other abnormal situation occurs, the fence can immediately issue an alarm and notify relevant personnel through various means (such as sound, light, remote information, etc.).

[0114] Improved security: Through multiple security protections and precise identification and authentication systems, the fence significantly improves the level of security protection and effectively prevents illegal intrusion and unauthorized access.

[0115] Enhanced flexibility: The fence's deployment and folding mechanism enables it to be flexibly adjusted according to different needs and scenarios, meeting both safety protection requirements and adapting to the needs of different working environments.

[0116] Easy to manage remotely: With powerful remote management capabilities, managers can monitor and control the status of smart fences anytime and anywhere, greatly improving management efficiency and response speed.

[0117] Optimize user experience: The automated and intelligent features of the fence provide users with a more convenient, efficient, and secure experience. Users can enjoy comprehensive security protection without complicated operations.

[0118] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's description and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
